WISE Launch Delay
WISE Launch Delay

(Source: NASA/JPL)

The launch of NASA's Wide-field Infrared Survey Explorer (WISE) mission is now rescheduled for Dec. 14, with a launch window of 6:09 to 6:23 a.m. PST (9:09 to 9:23 a.m. EST). The first launch attempt scheduled for Dec. 11 was delayed due to an anomaly in the motion of a booster steering engine.

Mission managers have implemented a plan to completely resolve the anomaly. This plan includes removing and replacing a suspect component on Friday, Dec. 11, allowing the Delta II to be ready for Monday's launch attempt. The current weather forecast calls for an 80 percent chance of acceptable weather during the launch window.

WISE will circle Earth over the poles, scanning the entire sky one-and-a-half times in nine months. The mission will uncover hidden cosmic objects, including the coolest stars, dark asteroids and the most luminous galaxies.
